Gentoo Linux Security Advisory

Title: imlib2: Buffer overflows in image decoding (GLSA 200501-19)
Severity: normal
Exploitable: remote
Date: January 11, 2005
Bug(s): #77002
ID: 200501-19

Synopsis

Multiple overflows have been found in the imlib2 library image decoding routines, potentially allowing the execution of arbitrary code.

Background

imlib2 is an advanced replacement for image manipulation libraries such as libXpm. It is utilized by numerous programs, including gkrellm and several window managers, to display images.

Affected Packages

Package: media-libs/imlib2
Vulnerable: < 1.2.0
Unaffected: >= 1.2.0
Architectures: All supported architectures


Description

Pavel Kankovsky discovered that several buffer overflows found in the libXpm library (see GLSA 200409-34) also apply to imlib (see GLSA 200412-03) and imlib2. He also fixed a number of other potential security vulnerabilities.

Impact

A remote attacker could entice a user to view a carefully-crafted image file, which would potentially lead to the execution of arbitrary code with the rights of the user viewing the image. This affects any program that utilizes of the imlib2 library.

Workaround

There is no known workaround at this time.

Resolution

All imlib2 users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.2.0"
